Practical benchmark
With 8% waste, a 30 L keg gives about 27.6 L. At 400 ml per glass, that is roughly 69 sellable serves.
Beer
How many glasses can you really sell from a keg?
Keg yield depends on litres, pour size, foam loss and line waste. A 30 L keg rarely gives 30 L of sellable beer.
Use with draft beer cost
Once you know real yield, divide keg cost by sellable serves to price each glass with a sustainable margin.
